In this part of Edd China’s classic car health checks video series, Edd looks at classic car interiors and runs through what you need to check for roadworthiness. In this video Edd runs checks on the steering lock, dashboard lights, power assistance (if fitted), as well as looking at the steering wheel itself to check it hasn’t deteriorated over time. He demonstrates how to check for sponginess in the brake pedal and that the handbrake latches securely.

Around 10% of classic car MoT failures are related to the driver’s view of the road, so Edd checks the wipers haven’t perished over time and that new lifeforms haven’t grown in the washer fluid. Finally Edd checks the seat belts and the seats’ structural integrity.

Valves are highly important for the optimal performance of a car’s engine. In this class, Ed teaches you how to inspect and adjust valve clearances to guarantee they are set in the proper spot for fluid, unimpeded engine motions.

In the final step of the engine decoking process, you’ll learn to reassemble the head, replace a new gasket, and remount the cleaned and decoked components onto the engine block. Ed walks you step by step through the finishing methods needed to put the cylinder head back together and make sure everything is properly affixed and operational.

In the previous class, Ed showed you how to clean the valves and prepare them for reinsertion into the head. Now, you’ll learn how to lap in the valves using grinding paste and then decoke the engine in order to increase its efficiency and ensure top-notch engine performance for another several thousand miles. Ed introduces the tools you need to complete this process and then shows you how to use them.
